the thread dressing liquid. A thread moistening wheel 12 of cork orother suitable material is mounted to rotate with the lower portion ofthe wheel immersed within the thread dressing liquid contained in thebasin 10. The axle 13 of this wheel 12 is removably mounted in suitablehalf bearings in the sides of the frame 14. This wheel is provided witha circumferential groove 15 for receiving the thread as it leaves thedelivery mechanism. A suitable guiding eye 16 is provided for thethread, which eye is supported in the plane of the moistening wheel 12for guiding the thread on to the wheel from its delivery spool or bobbin3. A brush 1'? is provided for removing the superfiuous moisture fromthe thread after it has passed over the top of the moistening wheel 12,which brush is secured to the frame 14. A guide 18 is provided forguiding the thread from the wheel to the brush 17. The thread as itleaves the brush 17, passes around an idler To all whom it may concernBe it known that I, WILLIAM C. KEY- WORTH, a citizen of the UnitedStates, and resident of Paterson, in the county of Pas saic and State ofNew Jersey, have invented a new and useful Improvement inThreadFinishing Machines, of which the This invention relates to animprovement in thread finishing machines and is more particularlydirected to certain improvements in the heaters in that type of machineshown, described and claimed in my Patent No. 991,856, issued May 9,1911, and entitled improvement in thread finishing machines.

The object of my invention is to provide individual thread heatershaving thread engaging surfaces of highly polished material of thatcharacter which will be proof against the moisture and acids used in thetreatment of the threads.

A practical embodiment of my invention is represented in theaccompanying drawings in which,

Figure 1 represents a thread finishing machine in end elevation with myimproved heater applied thereto. Fig. 2 is a view in side elevation ofthe ma chine with a portion intermediate its end broken away. Fig. 3 isa view in side elevation of one of the heaters. Fig. 4 is an endelevation of the same, Fig. 5 is a vertical central section taken in theplane of the line AA of Fig. 4, looking in the direction of the arrows,and Fig. 6 is a transverse section taken in the plane of the line B-B ofFig. 5, looking in the direction of the arrows.

Each thread delivery mechanism comprises a support 1 carried by the main'rame 2 for the thread delivery spool or bobbin 3, which spool or bobbinis held under the required frictional tension by the arm 4. Each threadwinding mechanism comprises a support 5 carried by the machine mainframe 2 for the winding spool or bobbin 6, which spool or bobbin isengaged by a drum 7 carried by a rotary shaft 8. A traverse bar 9 iscarried by the machine as usual for guiding the thread as it is woundupon its spool or bobbin.

The means which I have shown for moistening each of the threadscomprises a basin 10 carried by the main frame 2 of the machine, whichbasin is adapted to contain I thence passes downwardly through a guideeye carried by one arm 21 of an oscillating lever, the other arm 22 ofwhich is engaged by a longitudinally reciprocating bar 23 supported onroller 24 of the main frame 2 of the machine. The reciprocating movementof the bar 23 is imparted from one of the rocking levers 25 which impartthe longitudinally reciprocating movement to the traverse bars 9. In thepresent instance a connection 26 is provided between one of these levers25 and the bar 23. The thread as it leaves its eye 20 of the rockinglever 21, 22, passes downwardly along the outer surface of my improvedheater to be hereinafter specifically described, from thence around anidler pulley 28, then upwardly along the inner surface of the saidheater and finally around an idler pulley 29 on its way to the threadguide 30 on the traverse bar 9 of the thread winding mechanism.

The main steam inlet pipe 31 is provided with branch pipes 32 whichextend along within the branch exhaust pipes 33 which are connected tothe main exhaust pipe 34. These inlet and exhaust pipe branches arelocated along opposite sides of the machine below the vertical heaters27. Branch steam inlet pipes 35 extend upwardly into the interiors ofthe heaters 27 to a point roller 19 mounted in the frame 14 and from\Vhat I claim is: 1. In a thread finishing machine, a heater comprisinga body and a cap, a thread polishing band surrounding the body and capnear the top of the same. Exhaust branch pipes 36 connect the bottoms ofthe heaters with the hor zontally arranged branch exhaust pipes 33, thesaid pipes 36 surrounding and being spaced from the steam and yieldingmeans interposed between the pipes 35. Each heater 27 is provided withbody and cap for removably holding the a thread polishing band 37 madeof some band in position around the heater.

rust-proof and acid-proof material, such, 2. In a thread finishingmachine, a heater comprising a. body and a cap, a thread polishing bandsurrounding the body and cap and yielding means tending to force the capaway from the body of the heater for removably holding around the heaterunder tension.

3. In a thread finishing machine, a heater comprising a body and a cap,a'thread polishing band passing over the cap and under the bottom of thebody, and yielding means interposed between the body and cap for holdingthe band snugly in position on the heater.

for instance, as illuminum. By the term acid-proof I wish to beunderstood as referring to any material which is proof against the acidsused in thread finishing. This polishing band 37 is removable and may bereplaced from time to time without disturbing the heater. This polishingband passes over the outer and inner faces and around the top and bottomof the heater and is held in position by means of a spring 38 interposedbetween the body of the heater and a cap 39 at the top of the heater.

It will be seen that by the provision of heaters as herein described,the heaters may be made of any desired material such, for instance, ascast iron and the surfaces into contact with which the threads arebrought may be applied to the heaters, thus producing not only aneconomical arrangement but also one which will permit of providing thethreads with a very high luster.
